BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a type of sheet-type electronic thermometer, and in particular, it is attached to an object to be measured (for example, human skin or oral surface, indoors / outdoors, container surface, bathtub inner / outer surface) or left unattended. The present invention relates to a sheet-type electronic thermometer that measures the temperature of an object to be measured quickly, conveniently and easily.

2. Description of the Related Art As is well known, in the area of human body temperature measurement,
Several different electronic thermometers have already been developed, including hard pen thermometers, soft pen thermometers, nipple thermometers, and infrared ear thermometers. Most of the principles of most electronic thermometers are that thermistors or other heat-sensitive elements make use of the basic principle that the resistance value itself changes at different temperatures, and can be obtained by conversion. is there. The measuring time is about 60 seconds, that is, the measuring time is relatively long, and the subject is likely to feel unsuitable, especially for some use groups, such as infants. In addition, the ear thermometer uses an infrared thermosensitive element to achieve the effect of rapid measurement, but changes in the operating environment temperature and the complexity of the operating method affect accuracy (the structure of the ear canal is curved. Therefore, it is difficult to attach the sensitive element to the skin of the ear, and if the change in the environmental temperature is too large, the reaction of the detecting element with respect to the temperature will be in error.).

The operating steps of the electronic thermometer described above are usually
Disinfection of probe cover, activation, entry into standby state, leaving at measurement position (usually oral cavity, armpit, anus or skin surface),
Including measurement and display of measured values, the display unit is Celsius or Fahrenheit. As a result, when these electronic thermometers are used, the person to be measured is usually awake and the person to be measured has to stop other activities to make a measurement. , Left at the measurement position, thermal equilibrium, etc.), and for each measurement, a constant measurement time is persistent. Therefore, many problems occurred in measurement.

In addition, in the area of non-human body temperature measurement, electronic thermometers for indoor and outdoor have already been developed, for example, bath thermometers and baby bottle thermometers. Many of these thermometers are integrally molded, for example, in the case of an outdoor thermometer, the measurer needs to be outdoors or in close proximity to the thermometer, or the thermometer must be a fluid food product (such as a baby bottle). The temperature value cannot be read unless it is immersed in a thermometer.
This is not only inconvenient and hygienic, but it also has potential safety issues, especially when making many high temperature measurements, such as hot water or hot vessels, as you must be close enough to hot objects. ing.
